Just bought Turbo 400 trans behind a Chev 400 smb, has been sitting for a year.. Have run it for short periods about 6 times so far, twice when shut down it has squirted trans fluid out through the dip / fill pipe.. Have been told it could be either a blocked breather (easy fix) or the tourque converter is back filling into the trans..
I understand normaly you could expect about half the torque conv fluid to drain back.. When cold and not running the fluid level is about 2 inches above the "Hot Full" mark. Level when hot and running is on the "Add 1 pint" mark.. Anyone else heard of or struck this before..

Thanks Kultulz, we think it was the breather as it has now settled down. Will be going to the shop to have filter done etc, once on the road. The tranz is running a cooler but does not have a temp guage (yet).

when i overfilled the tranny in my jeep, it looked in between the hot and cold mark all the time, but when i cruised on the highway the fluid would pour out the fill tube. i drained a good quart out and it worked fine.

does this only happen when your on the highway when your trannies getting its ***** kicked?

hope this helps, if its not the fluid level then it must be a blockage of some kind. goodluck

sandman the problem is a plugged breather, not a filter problem. the breather helps control the expansion and contraction of the trans fluid, with the breather plugged it will push the trans fluid out the dip stick tube.

Thanks guys, we now have it sorted. There were two problems. It had not been run for 12 mths and there were air locks through the trans causing problems, and the breather was blocked. Is now as sweet as..
